1. Applications of Diversity and the Self-Attention Mechanism in Neural Networks
Sammanfattning : This thesis covers three contributions in applications of neural networks. The first is related to diversity and ensemble learning, while the other two cover novel applications of the self-attention mechanism. An important aspect of training a neural network is the choice of objective function. LÄS MER
2. Computational Methods for Image-Based Spatial Transcriptomics
Sammanfattning : Why does cancer develop, spread, grow, and lead to mortality? To answer these questions, one must study the fundamental building blocks of all living organisms — cells. Like a well-calibrated manufacturing unit, cells follow precise instructions by gene expression to initiate the synthesis of proteins, the workforces that drive all living biochemical processes.

3. The Salmonella enterica virulence : its role in bacterial adaption to mammalian and protozoan cells
Sammanfattning : Salmonellae are Gram-negative enteric bacteria and facultative intracellular pathogens responsible for a diversity of illnesses in a wide range of hosts, including man. Many serovars of Salmonella enterica harbor a plasmid that enhances bacterial virulence in infection models, and that seems to promote extraintestinal infection in man. LÄS MER
4. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes
Sammanfattning : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution. LÄS MER
5. Simultaneous profiling of cell types and lineages in neuro- and gliogenesis
Sammanfattning : The mammalian brain consists of billions of highly specialized cells and trillions of connections between them. This immense complexity arises from a single layer of neuroepithelial progenitor cells. LÄS MER
